ADJUSTABLE LUBRI CATING MEANS Filed July 16, 1928 E. fiOHMA/Y gwuantozPatented Qct. 21, 1930 ITED STATES EMANUEL r'nonmnn, or GASTONIA, NORTHCAROLINA ADJ STABLE LUBRICATING MEANS Application filed uly 16,

My invention relates to a device for oiling the bearings of' spinningframes, roving frames and the like, and has for an object thereof theprovision of a wick for lubricating the bearing, said wick being mountedin a container and being adjustable with relation to the bearing and tothe container.

An object of my invention is to provide a lubricating device forspinning frames, roving frames, and the like in which there is mounted awick member adapted to engage 'the journal mounted in the bearing, saidwick member having a coiled spring closely fitting therearound andprojecting .into a lubricant container in which is mounted an enlargedcoiled spring, said enlarged coiled spring, .having a restricted portionadapted to engage the wick and the restricted portion of the enlargedcoiled spring being adapted to follow the coiled spring mounted aroundthe Wick so that the two springs serve as a thread and nut for adjustingthe wick with relation to the enlarged coiled spring.

Another object of my invention is to provide a lubricating device forspinning frames, roving frames and the like, having meansfor lubricatingthe bearings of the rollers mounted in the bearings by means of anadjustable wick mounted in a'suitable container and" communicating withthe surface of said bear.-

Some of the objects of my invention having been stated, other objects,will appear as the description proceeds, when taken in connection withthe accompanying drawings, in which Fi ure 1 is a side elevation of aroll 'sta-nd showing mydevic'e applied thereto, the height of the rollstand being cut down and the size of my device being enlarged;

Figure 2 is a vertical, cross-sectional view taken through a portion ofmy device;

Figure 3 is a cross-sectional View taken through the; stem portion of mydevice and looking downwardly, and showing the lubricatin g hole andvent hole exposed to view;

Figure 4 is a similar View showing the said holes closed by the washer.I

Referring more specifically to the drawing, the numeral 10 indicates aconventional roll cap l4 threadably secured on the'upper end 1928,Serial No. 293,135;

stand having the bearing portion 11 and in this bearingportion I drill ahole as'indicated at 12, in which I mount my device. My device consistsof the tubular cup 13 having the thereof, which cap has the neck portion15, the upper end of said neck portion being threaded as at 16 and thisneck portion has.

the hollow portion 17 inwhich I mount the wick 18, said wick extendingdownwardly into the. portion 13. Around this wick 18 I secure the coiledspring 19 by having the closely wound portion 20 engaging the upper endthereof, and the lower end is pressed into the wick as at 21. Within thecontainer 13 I mount the enlarged coiled spring 22, which has therestricted portion 23, which restricted portion is adapted t'o engagethe wick so that this portion 23 falls between the various portions ofthe coiled spring 19, the portion 23 serving as a nut and the coiledspring 19 serving as threads on the wick so that by turning the wickwith relation to the spring 22, the wick may be adj ustedwith relatlonto spring 22, and when the wick becomes worn away at its upper end, theportion 21 can be lifted out of the wick and the coiled spring 19 can beslid downwardly on the wick so that it is seen that the life of the wickis practically unlimited. The container 13 is adapted to be filled witha suitable lubricant and the portion 14 has the two holes 24 and 25therein, the hole 24 being adapted to have the lubricant passedtherethrough and the hole 25 allows the air to escape from within thecontainer 13 as the air is displaced by the entrance of the lubricant.Around the neck' portion 15 I loosely mount the washer 26, which has thebroken away portion on one side thereof,as shown in Figures 3 and 4,which washer has the upwardly projecting portion 27 so that when thecontainer is filled that a slight push on-the portion 27 will cause thewasher to assume theposition shown in Figure 4 and close the said holesto prevent lint and dirt from entering thelubricant chamber.

'In the drawings and specification I have set forth a preferredembodiment of my invention, and although specific terms are employed,they are used in a' genericanddescriptive sense only and not forpurposes; of limitation, the scope of the invention'bemg set forth inthe appended claims.

I claim:

1. In a device for lubricating a bearing, the combination of ahole insaidjbearing, a lubricant container secured in said hole, a passagewaybetween the lubricant container and the surface of said bearing, a wickmounted in the lubricant container and having a coiled spring securedtherearound forming a thread on said wick, a second coiled springmounted in the lubricant container and having a re stricted portionthereof adapted to engage the said wick between the coiled springsecured therearound'to permit relative adjustment between the wick andthe said lastmentioned coiled spring. i

2. The combination with a journal comprising the usual bearing, a holein said bearing,'a wick guid mounted in said hole, a lubricant containerdetachably secured to said ,wick guide, a wick loosely mounted in saidwick guide and-projecting into the container, a coiled spring" securedaround the wick forming a thread, a coiled spring mounted in thelubricant container and being adapted to threadably engage the wickbetween the coiled spring secured therearound to force' the same throughthe wick guide, the two coiled springs forming means for adjusting the'said wick with relation to the coiled spring mounted in the container.

3. In a bearing, a roller mounted for rotation in the bearing, a holepiercing the bearing,.an oil cup mounted in the said hole, a wickmounted in the oil cup and being adapted to press against the rollmounted in the bearin a coiled spring secured around the wickaiidforming a thread thereon, a sec- 5. In a lubricating device, a bearingadapted to receive a shaft, a hole in the said bearing communicatingwith the surface thereof, a lubricant container mounted in said hole, awick mounted in the said lubricant container and having its end adaptedto engage the said -shaft,.acoiled spring snuglysecured around the saidwick to re-inforce the wick and form- 'ing a thread thereon, an enlargedcoiled. spring mounted in the lubricant contamerond coiled springmounted in the oil cup and being adapted to threadably engage the wickand the first named coiled spring to permit relative adjustment of thewick and the second coiled spring. 1

4. In a lubricating device, a bearing, a

shaft adapted to be rotatably mounted in the bearing, a lubricantcontainer secured to the said bearing and having its interior portioncommunicating with the surface of the bears ing, a wick mounted in thelubricant container and having its upper end in engage
